Hello ANSI SQL uses double quotes only for SQL identifiers. For literals are used single quotes. like SELECT col AS "some strange sql column identifier", 'some string value' FROM "some strange sql table identifier" so for case sensitive or strange (is keyword, contains space) sql identifiers use double quotes, for string constants use single quotes. some other database uses [] or ` .
